Summary

The purpose of this study was to compare the accuracy and sensitivity of slow-pull capillary technique, traditional suction aspiration and non negative pressure puncture in the diagnosis of mediastinal and/or hilar lymph node enlargement by ultrasound bronchoscopic lymph node biopsy.

Conditions

Interventions

PROCEDURE

Endobronchial ultrasound-guided transbronchial needle Slow-pull capillary sampling

The slow-pull capillary technique was performed as follows: after identification and measurement of the target lymph node, a needle was used to puncture the lymph node with the stylet in place.At the same time, the stylet was slowly and continuously pulled to create weak negative pressure.

PROCEDURE

Endobronchial ultrasound-guided transbronchial needle aspiration

The operation steps are the same as above, but the negative pressure device of 10ml syringe is connected behind the puncture needle.

PROCEDURE

Endobronchial ultrasound-guided transbronchial needle capillary sampling

The operation steps are the same as above, but there is no negative pressure device behind the puncture needle
